[SOLVED] Issues with Linux 6.9.1 and i915 "CPU pipe A FIFO underrun"

Hi,
since the upgrade to Linux 6.9.1 I have this issue on my laptop where 9 times out of 10 it will boot fine until it reaches the login prompt and then it will start to flicker in cyan and magenta before showing nothing but a black screen. This happens with both the modesetting driver and xf86-video-intel and before X is launched. I log in via tty. In the rare case I get to log in before it turns black my display area will be shifted upwards a couple of pixels with the topmost pixels warping around to the bottom of the screen. However other than that it will run mostly without issues. I can even manually set the resolution in xrandr and the display area will be fine from then on. Running xset dpms force off will turn of the display as expected but the system will hang and not wake up again. I played some audio file to see if this would continue to play but no.
The one error journald logs is a kernel message I can also see on the login prompt:
kernel: i915 0000:00:02.0: [drm] *ERROR* CPU pipe A FIFO underrun
My hardware is an i5-8350U with integrated Intel UHD Graphics 620.
So far I've tried appending i915.enable_psr=0 as a kernel parameter as the wiki says it might solve "flickering" and what I'm experiencing before the screen turns black could be considered "flickering" in the broadest terms. It did not change anything however. Reverting to Linux 6.8.9 however fixes the issue.

If anybody has any ideas or insights I'd be very grateful.

Re: [SOLVED] Issues with Linux 6.9.1 and i915 "CPU pipe A FIFO underrun"

Do you have an xorg log from both a good and a bad boot?
https://wiki.archlinux.org/title/Xorg#General (I assume the LTS kernel will still work to provide a "good" log?)

X doesn't really seem to care one way or the other. That is if I get to start X in the first place. So this "bad boot" still gives me the "FIFO underrun" error, funky display area and becomes unresponsive when turning the display off but most boots on Linux 6.9.1 will become unresponsive before logging in via tty and therefore before X even starts.

Re: [SOLVED] Issues with Linux 6.9.1 and i915 "CPU pipe A FIFO underrun"

Alright, I got rid of xf86-video-intel. I only installed it trying to troubleshoot this particular issue in the first place.
The parameter that apparently "solves" this is intel_idle.max_cstate=1 wich is less than ideal...
I used all three and then eliminated one by one and so far it seems to work.
My i5-8350U is apparently a Kaby Lake Refresh chip affected by a hardware flaw... This is news to me as I've been using this same machine for a long time now and never had any issues before and it still works fine with earlier kernels.
I'll mark this solved and check if future updates make this parameter unnecessary in which case I'll add that info the my initial post.

So thanks for the help. Much appreciated.

Re: [SOLVED] Issues with Linux 6.9.1 and i915 "CPU pipe A FIFO underrun"

Your system doesn't crash per-se but apparently the applied power management is apparently at least momentarily too agressive and the display signal degrades.

"i915.enable_dc=0" alone doesn't work?
Does a lower c-state restriction, eg. "intel_idle.max_cstate=5"?
Do you have the same problem w/ the LTS kernel?
Do you use a userspace powermanagement tool like TLP?
You do have https://archlinux.org/packages/extra/any/intel-ucode/ intalled?

Re: [SOLVED] Issues with Linux 6.9.1 and i915 "CPU pipe A FIFO underrun"

Unfortunately neither "i915.enable_dc=0" nor  "intel_idle.max_cstate=5" help. Same behavior as without any parameters.
The LTS Kernel works absolutely fine. I've never had any issues with Linux 6.6 even when it was brand new either.
I don't use any userspace power management tools.
Yes, I have intel-ucode installed.
The microcode hook is the first hook after autodetect in my mkinitcpio.conf.
However I don't think it's doing much right now (no "microcode updated early" message during boot) because my BIOS is still receiving updates. The current one is four days old.

Re: [SOLVED] Issues with Linux 6.9.1 and i915 "CPU pipe A FIFO underrun"

The LTS Kernel works absolutely fine.

This and assuming 6.8 still works as well makes it less likely that this is a HW issue.

If this doesn't go away by itself you'd have to bisect between 6.8.9 and 6.9

Re: [SOLVED] Issues with Linux 6.9.1 and i915 "CPU pipe A FIFO underrun"

If you want help with the bisection the three kernels to initially test are:
To start off it would be good if you could verify that 6.8 works:

sudo pacman -U https://archive.archlinux.org/packages/l/linux/linux-6.8.arch1-1-x86_64.pkg.tar.zst

And that the 6.9 kernel does not:

sudo pacman -U https://archive.archlinux.org/packages/l/linux/linux-6.9.arch1-1-x86_64.pkg.tar.zst

The next package is the first one from the bisection itself:

sudo pacman -U https://pkgbuild.com/~gromit/linux-bisection-kernels/linux-mainline-v6.8.r8073.g480e035-1-x86_64.pkg.tar.zst

Re: [SOLVED] Issues with Linux 6.9.1 and i915 "CPU pipe A FIFO underrun"

@Seth
Yes, Linux 6.8 has worked all this time.
I tried both forcing framebuffer compression on and off (i915.enable_fbc=1 and i915.enable_fbc=0 as kernel parameters) to no avail.
It is my assumption that Linux 6.9 changed some things more radically than usual as this is not the only hardware I have issues with, just the most pressing as it is my daily driver.
So the next step will be the bisection which looks quite intimidating.

@loqs
Could you please elaborate on the last package? How did you get this one and how would I find packages like this myself?
